Full Production Quality Process
Raw Hair Sourcing: Ethically collected virgin hair from young women, unprocessed and healthy, preserving shine and durability.
Raw Hair Sourcing
Cuticle Direction: Match hair type, length, and thickness according to order specifications.
Cuticle Direction Check
Double Stitching: Sew hair bundles with double needles to keep roots aligned during bleaching. Tension must be just right—too tight affects color penetration, too loose causes hair loss.
Double Stitching
Bleaching: Lighten hair to the base tone. Hair is checked every 45 minutes. pH: 4.5–6.5. Water temp: under 50°C.
Bleaching Ph and Temperature Control
Coloring: Dye hair to match the specified color ring. Same pH and temperature controls as bleaching.
Coloring
Washed and moved to drying room for moisture removal.
Washing
Color Check: Verify against color ring (color deviation within 0.5 tone). Ensure evenness—no root-tip differences.
Color Check
Unstitch & Bundle Drawing: Remove stitches, draw bundles evenly, and divide into consistent weight & thickness per order.

100% Cuticle Remy Hair Guaranteed
We use only 100% cuticle remy hair – made up of natural, straight human hair. To ensure softness and durability, we optimize each strand by gently combing the hair cuticle and using a healthy cold-bleaching process.
While some suppliers may pass off chemically treated non-Remy wigs as Remy wigs, we don’t. Every batch of wigs is certified before production to ensure real hair cuticle alignment and quality.

From Six Key Checks to Total Quality Assurance
Color Consistency
Length Accuracy
Each strand is carefully measured to guarantee length accuracy as per the order. Inaccurate lengths affect both styling flexibility and customer satisfaction, so we reject any deviation, ensuring clients receive extensions that are uniform, consistent, and exactly as expected.
Weight Control
We weigh every finished bundle precisely to match the order specifications. This strict control ensures customers receive full-volume products without shortfall, which is crucial for maintaining the density, natural appearance, and premium feel of high-quality hair extensions.
Width & Thickness Check
We inspect the width and thickness (also known as range or volume) of the extensions to ensure consistency across bundles. Whether it’s tape, weft, or clip-in types, we verify that each product meets the expected density and style coverage requirements.
Breakage Inspection
To prevent breakage, we source hair from young, healthy donors and use cold bleaching methods that preserve cuticle integrity. During final inspection, any strands with excessive breakage or damage are removed to guarantee long-lasting, tangle-free wearability.
Tensile Testing
Each batch undergoes tensile testing to assess hair strength and elasticity. This ensures the extensions can withstand styling stress and maintain structural integrity over time. Our clients rely on this resilience for repeated installations and confident end-user satisfaction.
Responsible Practices, Reliable Quality
Ethically Sourced, Consciously Made
We don’t just verify quality — we trace it to the source. All our hair is 100% ethically sourced from Western China, where it is voluntarily donated or fairly sold. Our supply chain is fully traceable, ensuring dignity and fairness at every step.
Sustainable Manufacturing & Packaging
Sustainability guides every step we take. From water-saving dyeing to FSC-certified paper and soy ink, we prioritize eco-friendly materials. Our packaging is also optimized to reduce waste and minimize shipping impact.
People First: Fair Work and Inclusive Growth
We maintain certified fair labor practices, with 80% of our team and leadership being women. All employees work regulated hours with equal opportunities. Instead of celebrity marketing, we celebrate real hair professionals who help shape our products.
Employee Empowerment, Continuous Development
We invest in training, mentorship, and career development to support our team’s growth. Engaged, empowered people make better products — and stronger brands.
Certified for Ethics, Quality, and Safety
At Alpha, we proudly hold multiple certifications that demonstrate our commitment to ethical practices and product quality. Our hair products are environmentally friendly, cruelty-free, and ethically made. We are committed to an employee-friendly environment, especially supporting female employees. In addition, all testing tools, weighing equipment, lithium battery equipment, and hair extension accessories are certified for safety and accuracy.
